The invention discloses an environment-detecting spherical robot with a plurality of modes of motion, which is driven by wind power. The invention relates to the mechanical technical field, the purpose of the invention is to employ the robot to self-select the motion modes of rolling, floating and the like according to different terrain environments under wind actions, and the robot has the advantages of low energy-consumption and low cost. The robot mainly comprises a semicircular baffle plate device, a diaphragm cloth device, an outer layer air sac, an inner layer air sac and an inner core sphere system. The inner core sphere system is composed of an inner core sphere body, a hydrogen / helium reaction or liquid hydrogen / helium storage device, an air-feeding and air-bleeding device, an electropneumatic valve, a core control board, a power, a sensor group, a wireless transceiver module and the like, the core sphere system is used to detect environmental information and to be in wireless communication with the outside world, further, the core sphere system is used to control and realize the air-feeding and air-bleeding, and to enable the robot to be provided with two motion modes ofpure rolling and floating. The environment-detecting spherical robot can be used to detect the ground environment such as Polar Regions and deserts and the environment of planetary surface, and the environment-detecting spherical robot also can be used in the field of investigation, entertainment, military affairs and the like.

The invention discloses a three-dimensional multi-layer cable box which forms a three-dimensional multi-layer winding and wiring space through a multi-layer hemispherical structure, and can flexibly adjust the angle of the winding column to meet different erection requirements. The multi-layer cable box is characterized in that one end of the fixing stud is fixedly placed in the middle of the top of the fixed base, the top of the protective cover is provided with a mounting hole, and the protective cover is placed on the fixing stud through the mounting hole , the protective cover is a hemispherical structure, the bottom of the protective cover is flush with the fixed base, a plurality of threading grooves are equidistantly opened on the bottom of the protective cover, and the other end of the fixed stud is screwed with a fixed lock cap , a plurality of arc-shaped covers are sleeved in the protective cover, the number of the arc-shaped covers is at least two, the arc-shaped covers are of a hemispherical structure, and the plurality of arc-shaped covers are concentric, and the plurality of arc-shaped covers are concentric. The diameter of the arc-shaped cover gradually increases from inside to outside, and the bottom of the arc-shaped cover is flush with the bottom of the protective cover.

The invention provides a cabinet air conditioner and an air outlet control method of the cabinet air conditioner. The cabinet air conditioner comprises a shell, a front air outlet structure and a top air outlet structure, wherein at least one air duct is formed in the shell; the front air outlet structure is provided with a front air outlet communicating with the air duct and is connected with a first rotating structure; and the top air outlet structure is arranged at the upper end of the shell and provided with a top air outlet communicating with the air duct, and the top air outlet structure is connected with a second rotating structure. The front air outlet structure comprises a front air outlet frame. The front air outlet frame comprises an air shield which is formed at the front air outlet. A receding hole matched with the front air outlet is formed in the shell. The first rotating structure comprises a first driving motor, a first driving gear and a driven gear, wherein the first driving motor, the first driving gear and the driven gear are arranged at the upper end of the front air outlet frame, the driven gear is fixedly connected to the front air outlet frame, the first driving gear is engaged with the driven gear, and the front air outlet is driven to right face the receding hole or the air shield is made to block the receding hole. The air-conditioning effect of the cabinet air conditioner is good, and the air outlet sealing effect is good.

The invention discloses an engine fan, which includes a metal disc (1) connected with the transmission shaft of an engine, wherein a plastic ring (4) is formed on the edge of the round disc through injection molding and wrapping; seven to ten blades are non-uniformly distributed on the circumference of the plastic ring, the angles of the blades are variably twisted corresponding to the rotary center of the round disc, the root parts and the chain edges of the blades are connected through strength structures, the areas of the blades are gradually enlarged from inside to outside, and the cross sections thereof are gradually lessened from inside to outside. The engine fan overcomes the defect of the conventional fan that the heat dissipation is not possible as the air can't enter the center of the hub, and removes the air intake dead angle; and the root parts of the blades are structurally strengthened, the air intake amount is increased, and the weight is reduced for one third.
